310T Practice Exam (2025-2026)
Questions with Actual Answers.
1. The shift lever vibrates and produces a noise that is audible from the transmission only while
under deceleration. What is the likely cause?
a. Brinelled U-joints
b. Slip joint lacks lubrication
c. Defective clutch
d. Driveline out of phase - Answer b. Slip jount lacks lubrication
2. The surface contact area of a ring & pinion gearset is "centered" upon the gear teeth, but the
gear-contact is too close to the top-land. What procedure is required in order to provide the
correct gear-tooth contact pattern?
a. Move the pinion away from the crown gear
b. Move the ring towards the heel
c. Move the crown towards the root
d. Move the pinion towards the crush sleeve - Answer c. Move the crown towards the root
3. As the clutch is engaged, there is a noise emitted from that area. This noise dissipates once
the clutch is depressed. What is the probable cause?
a. Worn pilot bearing
b. Damaged release bearing
c. Worn input shaft bearing
d. Lack of lubrication to the output shaft - Answer C. Worn input shaft bearing

a. It will only engage on sharp turns
b. It can only be engaged at high speeds
c. It can only be engaged with the vehicle stopped and the parking brakes on
d. A damaged shift fork lever - Answer d. A damaged shift fork lever
5. What would cause an automatic transmission to stall at low speed operation?
a. Improper convertor clutch operation.
b. Forward clutch slippage
c. Insufficient pump pressure
, d. Low engine power - Answer d. Low engine power

from the drive line. What is the probable cause?
a. Brinelled u-joints
b. Slip yolk splines are seized
c. Driveline is out of phase
d. Worn clutch - Answer a. brinelled u-joints
7. When the operator selects the "high-range" of a two speed inter-axle unit, the unit wil not
engage. What is the probable cause?
a. Nothing as it will only engage on turns
b. It will engage only when the vehicle is motionless
c. The driveline is out of phase
d. The shift fork is bent - Answer d. The shift fork is bent
8. During normal operating conditions, a noise is heard from the clutch / transmission assembly.
Upon depressing the clutch pedal, the noise is reduced or eliminated. What is most likely the
cause?
a. Worn pilot bearing
b. Worn input shaft bearing
c. Counter-shaft bearings are deteriorated
d. Release bearing requires an adjustment - Answer b. Worn input shaft bearing
9. A high pitch rattle is heard from the clutch area while the vehicle is moving, the noise only
gets worse once the clutch is depressed. What is the probable cause?
a. Release bearing
b. Pilot bearing
c. Input shaft bearing
d. Output shaft bearing - Answer a. release bearing
